Now my school team are safely home I will add the full list, hopefully without more mistakes.

U19 School Champions: Reading School
Runners up (winning the Richard Haddrell Trophy): RGS Guildford
3rd = Hampton School, Nottingham High School, City of London School
Plate winners (best performance by a first round loser): Brighton College

An interesting and perhaps unique pairing method. A 16 team Swiss over 4 rounds, but as it's a team competition, ties can be broken the traditional way by board count or bottom board elimination. There will only ever be two teams on 3/3 after three rounds, so you can have a head to head for the trophy and runner up.
